Gustav Mahler, Symphony No. 4 in G major, 4th Movement. Vienna Philharmonic Orchestra, conducted by Leonard Bernstein (1968). Soprano, Edith Mathis. I admit I usually strain the likeability factor around here with Mahler posts . . .
This is a Sunday special because it’s a song about heaven. As the Wikipedia entry notes,
The fourth movement opens with a relaxed, bucolic scene in G major. A child, voiced by a soprano, presents a sunny, naive vision of Heaven and describes the feast being prepared for all the saints. The scene has its darker elements: the child makes it clear that the heavenly feast takes place at the expense of animals, including a sacrificed lamb.
From 7:40 is the softest wind down of any symphony I know, except for Mahler’s Ninth.
